Transform your voice – live!
From the studio to the stage, the Roland Aira Compact E-4 is the ultimate performance tool for vocalists, beatboxers and MCs. Basing its design on its sibling the VT-3, the E-4 incorporates all the same tools and features in a compact and portable design. Boasting an intuitive interface with hands-on controls; the E-4 is ideal for live performances as well as studio work. Shape and transform your voice using the pitch and formant sliders or dial-in rhythmic effects using the ‘Scatter’ knob. You can also shape your sound further using the low-filter and noise-gate to eliminate any unwanted sounds or low-end rumble.
From real-time pitch correction to a musical harmonizer and even a vocoder; the E-4 has everything you need to create powerful vocal performances. If you’re a singer, you can use the harmony button to add ethereal harmonies to your songs/performances. There is even an onboard vocoder so you can capture the sound of the 80s, championed by Roger Troutman and used in countless hit records from that era.
24-second looper with advanced controls and effects
Capture your inspiration when it strikes with the onboard looper, providing 24-seconds of recording time with unlimited overdubbing. This opens a world of possibilities when it comes to creating loops, sequences and even full-blown vocal pieces. If you’re a beatboxer, this looper can be great for building up loops from the ground up. For example, you could lay down a drum beat then add a bassline, then a melody; all using your voice! Championed by the likes of Beardyman, this live-looping process is made easier than ever with the E-4
Not only that, but you can add some texture and process your vocals with a range of studio-grade effects on offer. Add some depth to your sound using the reverb or echo effect. There is also a tempo-synced delay and an array of chorus effects to choose from.
Portable design with versatile connectivity
Designed for musicians and performers on the go; the Roland Aira E-4 features a highly compact design that will fit in your lap and be stored easily within most backpacks. Play and perform wherever you go thanks to the built-in Lithium-ion battery, which provides up to 4.5 hours of playback from a full charge. Not only that but the housing of the beat machine is constructed using robust materials to ensure a durable enclosure. Roland has also used high-quality components throughout the manufacturing process including premium-quality rubber pads for the various controls, ensuring a long lifespan.
The rear panel of the Aira Compact E-4 features a wide variety of connection options including audio, MIDI and sync I/O, as well as an AIRA Link port for connecting multiple Aira Compact units together.
